"Stone Building Game"
Interesting early 20th century stained stone building set. This one appears to be complete (perhaps a piece has been replaced, I'm not sure). Also complete with its manuals and example images. Box made of solid, sturdy material. Considering the size and material, the whole thing is quite heavy. Length 37.5 cm Width 28 cm Thickness. 5.5 cm
